2" 0 all whom it may concern.-

Be it known that I, VIoToR H. BECKER, residing at Chicago, in the countyof Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Distributing-Valves, of whichthe following is a full description, reference being had to theaccompanying drawlngs, in which- Figure 1 is a section; Fig. 2, a topView, some parts being shown in section; Fig. 3, a

front elevation; Fig. 4, a top View of the plug 1 removed from the otherparts.

In refrigerating-machines in which ammomm or other fluid is used it iscommon to distribute the fluid from a header to a series of coils orpipes, each passage from the header to each coil being controlled andregulated by a valve. As such valves have heretofore been constructed,the opening has been large, and it has been difficnlt to properlyregulate the flow of the fluid, as a slight movement of the valvegreatly changes the size of the passage which it controls.

The object of my invention is to provide a valve which, when open, willpresent a small opening of about the proper size to allow the des1redquantity of fluid to pass, which can be easily closed and opened, whichcan be easily cleaned in case the passage becomes closed or clogged,which I accomplish as illustrated in the drawings, in which- A 1s acasting having a passage, or, through it. b are screw-threaded openingscommunicating with the passage (1, into which openings short tubes 0 aresecured. These tubes and the parts b take the place of the ordinaryheader, and the fluid is to be introduced into this header in a suitablemanner.

B is a cap, which enters the recess at the top of the casting A. Thiscap is provided with flanges d, one on each side.

6 are corresponding flanges on the casting A.

f are screw-threaded bolts, by means of which the cap .8 is secured inplace.

9 1s a packing.

h isa plug fitting into the walls ofA, as shown in Fig. l.

i is the stem of the plug.

j is a space beneath the lower end oft-he plug.

is is a passage through the plug, which is tapering, and. is very smallat one end, as shown in Fig. 2, and indicated by dotted lines in Fig. 1.

0 is a pipe leading from the valve to the coil. Zare flanges upon thelower end of the cast -ing A.

m is a screw-threaded coupling upon the pipe 0, provided with flanges a,corresponding with Z.

0 are bolts.

1) is packing.

r is a thumb-screw fitting an opening, .9, in the wall of the casting A,opposite to the plug h. A similar thumb-screw and hole are provided onthe opposite side of the casting. (Not shown in the drawings.)

The dotted circular line in Fig. l on the plug indicates the position ofthe thumb-screw r and the hole which it closes.

In use, when the plug is in the position indicated in Fig. 1, the fluidwhich flows from the header will pass through the small hole in theplug, then through the passage 70 in the plug to the passage a, thenthrough the passage a and the pipe 0 to the coil with which 0 isconnected. part of the passage a which is lettered a, so as to close theopening into the plug, it can probably be removed by first turning theplug into the position shown in Fig. 2, when the accumulation will passinto the large opening 70, and then, by turning the plug back to theposition shown in Fig. l, the pressure of the fluid will probably forcethe accumulation from k. The passage through the plug can also bereadily cleaned by turning it one-quarter of the way around, which willeffectually close the passage a, and then, after removing the set-screwsr, a wire can be run through the holes 8 and the passage k.

The passage can be cleaned without removing the plug, without any escapeof fluid.

The small hole in the plug must be atfirst made as nearly as possible ofthe proper size, to permit the flow of the required quantity of fluid.

Where a number of these valves are used With a common header, the fluidfrom the header will pass to each one of the valves, and a uniformquantity will flow through each valve. This valve may be used in otherplaces where it is desirable to provide for the flow of a small uniformquantity of fluid.

If solid matter accumulates in that For convenience the position of thepassage is through the plug may be indicated on the top of the stem t,as shown by dotted linesin Fig. 4.

I disclaim a distributing-valve plug having an inlet-chamber at one sideand a contracted exit-passage at the opposite side, and confine myselfto the plug with the special form of aperture herein shown.

What I claim as new, and desire to secure by Letters Patent, is-

In -a distributing-valve, the casing or body having passages on a, hole8 in one of its sides, and plug 1', fitting to said hole, in combination
